우리나라 동해안에서의 높은 너울에 대한 다중지점 관측

Abstract

In recent several years, extremely high swell are occasionally occurred in the East Sea of Korea. In this paper, the multi-station wave observation records of high swell event during 23th to 25th February in 2008 and their significant characteristics are reported. At that time, three people were dead at the breakwater of Anmok harbor by being swept by the high swell. The reason for appearance of the high swell is the strong extra-tropical low pressure system that is rapidly developed in the East Sea of Korea. Such a strong low pressure system can be well developed in winter season and may cause severe disaster on the coast of Korea and Japan. Hence, it is needed to enhance predictability of the high swell by carrying out researches in order to more thoroughly understand the detailed mechanism related to the development of winter season low pressure system.
